Abstract
Description
Technical Field
[0001] This utility model belongs to the field of geological exploration technology, and in particular relates to a stratified sampling device for geological professionals. Background Technology
[0002] Geological survey sampling devices are mainly used for stratified sampling in boreholes, and are particularly suitable for obtaining undisturbed samples in loose strata, sand layers or strata below the groundwater level.
[0003] Existing sampling devices for geological exploration typically use cylindrical tubes to insert into the soil, and then sample the sand and gravel. However, when sampling is required at different depths, staff need to take samples sequentially, which requires multiple operations, making the process cumbersome and inefficient. Therefore, we propose a stratified sampling device for geological professionals. Utility Model Content
[0004] The purpose of this invention is to provide a stratified sampling device for geological professionals. Specifically, after assembly, the operator rotates the handle to rotate the sampling cylinder, causing the second inlet to rotate into the inner part of the outer cylinder, thus sealing it. The operator can then insert the outer cylinder into the soil. Next, the handle is rotated again, causing the second inlet to rotate to the position of the first inlet. At this point, sand and gravel in the soil will enter the collection trough for collection. Because the sampling cylinder has three sets of collection troughs, it can simultaneously sample at three different depths, reducing sampling steps and improving work efficiency. This solves the problem that existing geological exploration sampling devices require operators to sample sequentially at different depths, resulting in multiple operations, a cumbersome process, and low sampling efficiency.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a stratified sampling device for geological applications, comprising an outer cylinder with a fixing block at the top. The outer cylinder has a hollow interior, and a circular hole is formed at the center of the fixing block. A sampling cylinder is inserted into the circular hole at the center of the fixing block, and the sampling cylinder is inserted into the outer cylinder. The outer cylinder has three feed inlets (I) on its outer side, and the sampling cylinder has three feed inlets (II) on its outer side. Several partitions are fixedly connected to the inner wall of the sampling cylinder, and a collection groove is formed between every two partitions. After the sampling cylinder is inserted into the outer cylinder, the feed inlets (II) correspond to the feed inlets (I). Because the sampling cylinder has three sets of collection grooves, it can simultaneously sample at three different depths.
[0007] Furthermore, an internal threaded ring is fixedly connected to the bottom of the fixing block, and an external threaded ring is fixedly connected to the top of the fixing block. The outer side of the top of the outer cylinder is provided with threads, and the outer side of the top of the outer cylinder is threadedly connected to the inner wall of the internal threaded ring. The outer cylinder is fixed to the fixing block by connecting to the internal threaded ring through the threads, which facilitates the installation and disassembly of the outer cylinder and makes it easy to replace it in the future.
[0008] Furthermore, an internal thread handle is provided above the external threaded ring. The internal thread handle is sleeved on the outside of the sampling cylinder. The inner wall of the internal thread handle is threadedly connected to the outer surface of the external threaded ring. A first limiting ring is provided on the inner side of the internal thread handle, and a second limiting ring is provided above the first limiting ring. The inner rings of both the first and second limiting rings are fixedly connected to the outer surface of the sampling cylinder. After connecting the sampling cylinder to the outer cylinder, the internal thread handle is rotated clockwise to make it threadedly connected to the external threaded ring. The inner side of the first limiting ring is limited by cooperating with the external threaded ring. At this time, the first limiting ring does not need to be locked, which facilitates the rotation of the sampling cylinder.
[0009] Furthermore, a handle is provided at the top of the sampling cylinder, and a threaded shaft is fixedly connected to the bottom of the handle. A thread is provided at the top of the inner side of the sampling cylinder, and the top of the inner wall of the sampling cylinder is threadedly connected to the threaded shaft. The handle is connected to the sampling cylinder through the threaded shaft, which facilitates the subsequent rotation of the sampling cylinder.
[0010] Furthermore, the limiting ring one and the limiting ring two cooperate to limit the internal thread throttle. After the internal thread throttle is threadedly connected to the external thread ring, the sampling cylinder will be locked onto the fixing block by the limiting ring one. By locking and fixing the sampling cylinder, the free rotation of the sampling cylinder is prevented, which facilitates the subsequent sampling work.
[0011] This utility model has the following beneficial effects:
[0012] 1. This utility model features a sampling cylinder. After assembly, the operator rotates the handle to rotate the sampling cylinder, causing the second inlet to rotate into the inner part of the outer cylinder, thus sealing it. The operator can then insert the outer cylinder into the soil. Afterward, the handle is rotated again to rotate the second inlet to the position of the first inlet. At this time, sand and gravel in the soil will enter the collection trough for collection. Since the sampling cylinder has three sets of collection troughs, it can simultaneously sample at three different depths, reducing sampling steps and improving work efficiency.
[0013] 2. This utility model features an internal threaded handle. Specifically, when the inlet 2 on the sampling cylinder is inside the outer cylinder, rotating the internal threaded handle clockwise will squeeze the limiting ring 1, thus locking and fixing the sampling cylinder and preventing it from rotating freely. This makes it easier for workers to insert the outer cylinder into the soil. Furthermore, by disassembling the outer cylinder and rotating the internal threaded handle counterclockwise away from the external threaded ring, the sampling cylinder can be pulled upwards and removed. Different lengths of outer cylinders and sampling cylinders can be replaced to meet sampling needs at various depths.
[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0024] Please see Figures 1-5 As shown, this utility model is a stratified sampling device for geological applications, including an outer cylinder 1. A fixing block 11 is provided at the top of the outer cylinder 1. The interior of the outer cylinder 1 is hollow. A circular hole is opened at the center of the fixing block 11. A sampling cylinder 2 is inserted into the circular hole at the center of the fixing block 11. The sampling cylinder 2 is inserted into the interior of the outer cylinder 1. Three feed inlets 12 are opened on the outer side of the outer cylinder 1. Three feed inlets 22 are opened on the outer side of the sampling cylinder 2. Several partitions 23 are fixedly connected to the inner wall of the sampling cylinder 2. A collection groove 24 is formed between every two partitions 23. After the sampling cylinder 2 is inserted into the outer cylinder 1, the sample is fed into the outer cylinder 1. The second inlet 22 corresponds to the first inlet 12. After assembly, the operator turns the handle 21 to rotate the sampling cylinder 2, so that the second inlet 22 rotates into the inner part of the outer cylinder 1, which plays a sealing role. The operator can then insert the outer cylinder 1 into the soil. Then, the operator turns the handle 21 again to rotate the second inlet 22 to the position of the first inlet 12. At this time, the sand and gravel in the soil will enter the collection trough 24 for collection. Since the sampling cylinder 2 is equipped with three sets of collection troughs 24, it can simultaneously sample three different depths, reducing sampling steps and improving work efficiency.
[0025] The bottom of the fixing block 11 is fixedly connected to an internal threaded ring 13, and the top of the fixing block 11 is fixedly connected to an external threaded ring 131. The outer side of the top of the outer cylinder 1 is provided with threads, and the outer side of the top of the outer cylinder 1 is threadedly connected to the inner wall of the internal threaded ring 13.
[0026] An internal threaded handle 25 is provided above the external threaded ring 131. The internal threaded handle 25 is sleeved on the outside of the sampling cylinder 2. The inner wall of the internal threaded handle 25 is threadedly connected to the outer surface of the external threaded ring 131. A limit ring 251 is provided inside the internal threaded handle 25, and a limit ring 252 is provided above the limit ring 251. The inner rings of the limit ring 251 and the limit ring 252 are both fixedly connected to the outer surface of the sampling cylinder 2. When the feed port 22 on the sampling cylinder 2 is inside the outer cylinder 1, the internal threaded handle 25 is rotated clockwise to squeeze the limit ring 251, thus locking and fixing the sampling cylinder 2 and preventing it from rotating freely. This makes it easier for workers to insert the outer cylinder 1 into the soil. Furthermore, by disassembling the outer cylinder 1 and rotating the internal threaded handle 25 counterclockwise away from the external threaded ring 131, the sampling cylinder 2 can be pulled upwards and removed. Different lengths of outer cylinder 1 and sampling cylinder 2 can be replaced to meet the sampling needs at various depths.
[0027] The sampling cylinder 2 is provided with a handle 21 at the top, and a threaded shaft 211 is fixedly connected to the bottom of the handle 21. The top of the inner side of the sampling cylinder 2 is provided with a thread, and the top of the inner wall of the sampling cylinder 2 is threadedly connected to the threaded shaft 211.
[0028] Limiting ring 1 251 and limiting ring 252 work together to limit the internal thread throttle 25. After the internal thread throttle 25 is threadedly connected to the external thread ring 131, the sampling cylinder 2 will be locked onto the fixing block 11 by limiting ring 1 251.
[0029] One specific application of this embodiment is:
[0030] In use, the top of the outer cylinder 1 is threaded onto the inner threaded ring 13 at the bottom of the fixing block 11, so that the outer cylinder 1 is connected to the fixing block 11. Then, the sampling cylinder 2 is inserted from the top of the fixing block 11, so that the sampling cylinder 2 enters the outer cylinder 1. When the limiting ring 251 contacts the top of the outer threaded ring 131, the sampling cylinder 2 is connected. Then, the inner threaded handle 25 is rotated clockwise to make it threadedly connected to the outer threaded ring 131. The inner side of the limiting ring 251 is limited by cooperating with the outer threaded ring 131. At this time, the limiting ring 251 does not need to be locked, so that the sampling cylinder 2 can rotate. By limiting the limiting ring 251, the sampling cylinder 2 can be prevented from falling off. Finally, the handle 21 is threadedly connected to the top of the sampling cylinder 2 through the threaded shaft 211 at the bottom to fix the handle 21.
[0031] After assembly, the worker turns handle 21 to rotate the sampling cylinder 2, causing the second inlet 22 to rotate into the inner part of the outer cylinder 1. The surface of the sampling cylinder 2 then rotates to the position of the first inlet 12, thus achieving a sealing effect. At this time, the internal thread handle 25 is turned clockwise to squeeze the first limiting ring 251, thus locking and fixing the sampling cylinder 2 and preventing it from rotating freely. The worker can then hold the handle on the fixing block 11 and insert the outer cylinder 1 into the soil. When the outer cylinder 1 is inserted into the appropriate position, the internal thread handle 25 is turned counterclockwise to release the fixing of the sampling cylinder 2. Then, the handle 21 is turned again, causing the sampling cylinder 2 to rotate together, causing the second inlet 22 to rotate to the position of the first inlet 12. At this time, the sand and gravel in the soil will enter the collection tank 24 for collection through the first inlet 12 and the second inlet 22. Since the sampling cylinder 2 is equipped with three sets of collection tanks 24, it can simultaneously sample three different depths, reducing sampling steps and improving work efficiency.
[0032] After sampling is completed, pull the outer cylinder 1 out of the soil and turn the internal thread handle 25 counterclockwise away from the external thread ring 131 to release the sampling cylinder 2 from its fixation. Then pull the sampling cylinder 2 upward to separate it from the outer cylinder 1, so that the sample in the collection tank 24 can be taken out. By disassembling the outer cylinder 1 and the sampling cylinder 2, the outer cylinder 1 and the sampling cylinder 2 of different lengths can be replaced to meet the sampling needs of various depths.
